Name an environmental benefit of landscaping.

Landscaping offers several environmental benefits, and one of the most significant is its positive impact on air quality. Plants and trees engage in the process of photosynthesis, where they absorb carbon dioxide—a greenhouse gas—and convert it into oxygen, which is vital for human and animal life. This process not only reduces the amount of carbon dioxide in the atmosphere but also enhances overall air quality, making it cleaner and more breathable.

In addition, well-planned landscaping can help filter pollutants from the air, trap dust and particulate matter, and provide shade, which can mitigate the urban heat island effect. This illustrates how landscaping acts as a natural air purifier, supporting both ecological health and human well-being.

The other options do not align with the typical benefits of landscaping. For instance, while urban development can occur due to landscaping, it is not inherently an environmental benefit. Similarly, decreasing land availability and increasing noise pollution are negative impacts rather than benefits. Therefore, the correct answer highlights a key positive outcome of landscaping in relation to environmental health.
